(1 point) the average rates of change cannot be compared since f(x) is quadratic and g(x) is exponential. the estimated rate of change of g(x) is greater than the estimated rate of change of f(x) over the interval 1,2.39. the estimated average rates of change of both functions over the interval 1,2.39 are approximately equal. the estimated rate of change of f(x) is greater than the estimated rate of change of g(x) over the interval 1,2.39. check answer remaining attempts : 3
Answer
Explanation:
Step1: Definir la fórmula de tasa de cambio promedio
La tasa de cambio promedio de una función $y = h(x)$ en el intervalo $[a,b]$ es $\frac{h(b)-h(a)}{b - a}$.
Step2: Calcular la tasa de cambio promedio de $f(x)$
Para $f(x)=3.5x^{2}$, $a = 1$, $b = 2.39$. Entonces $f(1)=3.5\times1^{2}=3.5$ y $f(2.39)=3.5\times(2.39)^{2}=3.5\times5.7121 = 19.99235$. La tasa de cambio promedio de $f(x)$ es $\frac{f(2.39)-f(1)}{2.39 - 1}=\frac{19.99235 - 3.5}{1.39}=\frac{16.49235}{1.39}\approx11.865$.
Step3: Calcular la tasa de cambio promedio de $g(x)$
Para $g(x)=3.5^{x}$, $a = 1$, $b = 2.39$. Entonces $g(1)=3.5^{1}=3.5$ y $g(2.39)=3.5^{2.39}$. Usando una calculadora, $3.5^{2.39}\approx30.77$. La tasa de cambio promedio de $g(x)$ es $\frac{g(2.39)-g(1)}{2.39 - 1}=\frac{30.77-3.5}{1.39}=\frac{27.27}{1.39}\approx19.62$.
Step4: Comparar las tasas de cambio
Como $19.62>11.865$, la tasa de cambio promedio estimada de $g(x)$ es mayor que la tasa de cambio promedio estimada de $f(x)$ en el intervalo $[1,2.39]$.
Answer:
The estimated rate of change of $g(x)$ is greater than the estimated rate of change of $f(x)$ over the interval $[1,2.39]$.
